Re: heater water plumbing

["Mark Price" <mprice@xxxxxxxxxx>]

I wonder if this valve is still available?
I'd love to tap one into my S-10 to see if it would help keep it from puking heated air out of the heater box everytime I start it up in hot weather.

>The 1983 "TSM" is merely a supplement to the 1982 fullsize TSM. They work in tandem with each other---the 83 TSM only covers the "new" or different stuff for that model year. AMC was being cheap again, and figured reusing the 82 TSM would save a few bux.

From the rear port on the intake, a hose goes across and hooks up to the 4-way heater control valve. Yup, 4-way! Both sides of the heater core attach to this heater valve, which allows coolant to continue to flow through the intake manifold even if the heater valve is closed to keep coolant from the heater core. Of course this valve is vacuum operated. The larger (3/4") hose comes out of the heater core, attaches to this heater valve, then continues from the other side down to the port on the water pump.
